Frequently Asked Questions
Not necessarily. The title is intentionally ambiguous, as Jedi is both singular and plural. As stated in the opening crawl of The Force Awakens, Luke Skywalker is the last Jedi. TLJ Director, Rian Johnson has also confirmed this in interviews and via Twitter. In the first trailer for this film, Luke is heard saying "I only know one truth; it's time for the Jedi to end.", which could mean he refuses to train Rey to become a Jedi but may still train her in the use of the force, which would make Luke the literal last Jedi. However, if Luke trains Rey to be a Jedi, then they would both be the last.
Naturally, we can only speculate at this point. It's possible Luke is wracked with guilt over the massacre of the new Jedi Order he created. Twice the Jedi order has failed. It's likely that Luke has realized that the way the Jedi order utilizes only the light side of the Force isn't effective. So perhaps he wants to create a new order with Rey that is more in-between, embracing both the light and the dark (embracing "a larger view of the Force", "not just the dogmatic, narrow view of the Jedi", in a more honest context than those who would use such a sales pitch). Notice the symbolism of the first poster. Luke's face (light side) on one side, Kylo Ren's (dark side) on the other, with Rey in the middle separating the two and her lightsaber going from blue to red.
November 3rd, 2017: Re-wrote and tightened up the question "Does the title signify or foreshadow the end of the Jedi Order?" as it rambled on and on about things that didn't really have anything to do with the question. Nor did it provide any answers or theories based on information we know.
